1 answer:

Answer:

C

Step-by-step explanation:

We can multiply each equation by a constant so they'll equal either 15 or -15 since that is the LCM.

Since the answer choices want us to make the top a negative 15, we'll do that.

2x-5y=-21 \\ \\ 3(2x-5y)=(-21)*3 \\ \\ 6x-15y=-63

To make the y's cancel out, the second equation would have to have the y's coefficient equal 15.

Let's do that.

3x-3y=-18 \\ \\ -5(3x-3y)=(-18)*-5 \\ \\ -15x+15y=90

So the resulting equations are answer choice C.

what are the factors of 47 (cuz im STUPID and i dont feel like doing this cuz im working on geogrophy)
Hitman42 [59]

Hey there! I'm happy to help!

The factors are the numbers you multiply to get 47. And they can't be fractions or numbers with fractions. They have to be integers (numbers without fractions).

So far, we see that we can multiply 1 and 47 to get 47. To see if there are any more, we see what numbers 1-10 we can divide by.

We cannot divide by 2 because 47 is odd.

We cannot divide by 3 because it gives us 15.6666...

We can't divide by 4 because 47 is odd.

We can't divide by 5 because 47 does not have a 5 or 0 in the ones place.

We can't divide by 6 because 47 is odd.

We can't divide by 7 because it gives us 6.714285....

We can't divide by 8 because 47 is odd.

We can't divide by 9 because it gives us 5.2222

And we obviously can't divide it by 10.

Therefore, the factors of 47 are 1 and 47. A number whose only factors are 1 and itself is called a prime number.

I hope that this helps! Have a wonderful day! :D

Here's a graph of a linear function. Write the
nikklg [1K]

Answer:

y= 3/2x + 1

Step-by-step explanation:

slope intercept form is y=mx+b. the m is the slope and the b is the y intercept. the y intercept is 1, where it crosses the y axis. the slope is 3/2 because from the y intercept which is 1, you go up 3 and over 2 right.

Yes! That's exactly right.

8x-1+58+75=180

8x+132=180

8x=48

x=6 degrees

C because if you plug one into the other the answer comes out as x and that is how you know it is an inverse
